Object Storage Hybrid Infrastructure

S3 Object Storage features

Secure data centersIONOS Cloud offers maximum security thanks to encrypted, redundant data storage. S3 Object Storage is available in our highly secure data centers in Europe.
High reliabilityFor maximum reliability, IONOS Cloud runs your S3 Object Storage in a highly available setup and backs up your data with local replication. You also have the option to choose georedundant data storage. There’s a charge for primary and georedundant storage usage.
S3 Object Lock for long-term storageOnce an object has been stored, S3 Object Lock protects it from being deleted, modified or overwritten — for years if required. You configure the retention periods according to your needs. If a new version of the same file is uploaded, the system automatically creates an additional version of the document. In this way, S3 Object Lock makes your data auditable and meets the legal WORM ("Write Once Read Many") requirements for long-term data storage.
Individual access protectionYou control who accesses your S3 Object Storage. You can define access rights individually using access control lists, ensuring that your data security is maintained at all times.
Fast setupQuickly and easily integrate IONOS Cloud S3 Object Storage into your IT infrastructure by using our S3 API, Compute Engine's Data Center Designer, third-party SDKs, or an S3-compatible client to configure your S3 buckets or transfer your storage objects to the cloud.
